# Top 6 ABM agencies for B2B account campaigns

Sources checked 4 October 2026. Editorial fit assessments, not audited delivery scores.

## 1. The Marketing Practice

Connecting account campaigns to sales opportunities

Our first pick for an established B2B team that needs marketing and sales to act on the same account signals. Its published work gives buyers a concrete implementation to question, not just a list of services.

Its ABM service covers individual accounts, account groups and broader campaigns, with shared sales follow-up and measurement.

The Reltio case describes 6sense segments matched with Salesforce data and activated through LinkedIn and display. The reported 20% increase is actionable sales pipeline, not revenue.

Request a quote. No fixed fee on the reviewed ABM service page. Separate agency fees, media and software in the proposal.

Ask how accounts qualified, which period was measured and how sales handled the signals. Results from another client do not predict yours.

## 2. The ABM Agency

Testing a focused pilot before expanding

Second overall and our first option for a focused pilot. Its published process makes account selection and sales involvement explicit, which gives a buyer a useful basis for a brief.

The pilot page suggests about ten accounts and a four-to-six-month program. It describes using either the client’s technology or agency license instances.

Published services include individual-account and small-group campaigns, sales enablement and reporting.

Request a quote. No fixed pilot fee on the reviewed page. Ask whether platform access and media are included.

Confirm the launch date: the homepage says pilots can usually launch within 21 days, while the pilot page says 45–60 days. Launch time is separate from program duration.

## 3. Transmission

Creative and activation across an account campaign

Third for teams that need campaign ideas and delivery together. Its broad scope is useful when the bottleneck spans messaging, assets and channels rather than account strategy alone.

Transmission describes combining personalized individual-account work with broader account reach, supported by strategy, creative, sales engagement and analytics.

The ABM page points to work for Software AG, Henkel and HP. These are provider-published examples, not comparable performance scores.

Request a quote. No fixed fee on the reviewed ABM page. Request creative, production, activation and media costs separately.

Ask for the team assigned to your markets and which assets will be localized. A broad service menu does not establish what your contract includes.

## 4. Iron Horse

A scoped ABM plan with published starting prices

Fourth for a general agency search, but a useful first call when you need a defined planning engagement. Published scope makes the next conversation more specific than an open-ended retainer pitch.

Iron Horse covers account selection, buying-group research, content planning and sales handoffs.

Its ABM page describes OneStream work around audience needs and content journeys for a new segment.

Program planning from $25,000/segment. Eight-week Integrated ABM Program; execution, media management, analytics and optimization are add-ons. A separate eight-week GTM Assessment starts at $50,000.

The starting fee is not an all-in campaign budget. Request the cost of putting the plan into market before approving the planning phase.

## 5. MomentumABM (formerly Momentum ITSMA)

Strategic accounts and changes to how teams work

Fifth for a campaign brief, but the strongest fit here when the problem is how sales, marketing and service work around major accounts. A standalone ad campaign would be a narrower purchase.

MomentumABM is now part of Accenture Song. Its services cover account prioritization, major pursuits, revenue operations and change enablement.

The current site describes work across financial services, technology and professional services, including strategic-account programs.

Request a quote. No standard fee on the reviewed homepage. Scope consulting, enablement and delivery separately.

Confirm the current contracting entity and delivery team. Ask which recommendations the team will implement and which require internal change.

## 6. 2X

Adding people and processes to run account campaigns

Sixth for buyers comparing discrete agency projects, but a relevant option when an internal team needs recurring execution capacity. Judge the proposed working model as closely as the campaign idea.

2X describes account segmentation, intent-led campaigns, engagement scoring, campaign builds and collaboration with business development teams.

Its site links to JAGGAER and SAP examples involving 6sense. Intelligent Demand’s former website currently redirects to 2X.

Request a quote. No fixed ABM fee on the reviewed service page. Ask for team capacity, deliverables and software costs.

Ask who owns strategy, which specialists are dedicated to your account and how work is prioritized. Treat Intelligent Demand and 2X as a relationship to clarify, not two automatically independent bids.

## What does an ABM agency do?

An account-based marketing agency helps you choose target companies, understand their buying teams and coordinate marketing with sales. The useful output is a plan for specific accounts: who needs to hear what, through which channel, and who follows up. A list of contacts or an advertising audience alone is not the same service.

## Choose the approach before the agency

Use individual-account work when a few strategic deals justify deep research and custom material. Group accounts when they share a business problem and can use a common campaign with relevant variations. Broader account targeting needs reliable data and a repeatable follow-up process. Ask the agency to justify the effort per account against the potential value.

## How much should you budget?

The reviewed Iron Horse offer starts at $25,000 per market segment for an eight-week planning package, with execution and other services offered separately. This is one published offer, not an industry average. The other shortlisted firms did not publish a fixed fee on the pages reviewed. Compare the total commitment: setup, agency delivery, media, platforms, data, creative and internal time.

## What should a pilot include?

Agree on a named account list, the reasons for selection, the buying roles to reach and the content or offer for each stage. Assign a sales owner before launch. Document the current opportunity stage, relevant contacts and engagement so there is a baseline. Define what you will learn even if no deal closes during the pilot.

## How do you measure ABM?

Track whether you are reaching relevant people within the selected accounts, whether sales accepts the resulting conversations and whether opportunities progress. Report new and existing opportunities separately. Pipeline is potential business, not booked revenue. Compare results over a stated period and explain attribution instead of assigning every touched deal to marketing.

## What should you ask before signing?

Ask who researches the accounts, who writes and approves the material, who operates the platforms and who follows up with sales. Request a sample account plan and report. Separate platform licenses from service fees, check data ownership and export rights, and agree on what happens at the end of the pilot.
